A District woman apparently "conned" her way out of the Prince George's County Detention Center yesterday after spending only one night there, becoming the third prisoner in less than two weeks to escape from the three-month-old, state-of-the-art facility, a sheriff's department spokesman said.

"She was in {the jail} by 6 Friday night and out by 7:30 the next morning," said spokesman Irv Smith. The woman was captured by D.C. police about five hours later in a Southeast Washington home.

Bonita Blalock, 22, whose address was not known last night, escaped around 8:45 a.m. after convincing jail officials that she was on a weekend work program, said spokesman Irv Smith.

A jail official said the weekend work program is a form of alternative sentencing for people convicted of misdemeanors, who report to the jail at 6 p.m. Friday, perform public service jobs all weekend and are released Sunday at 6 p.m.

Blalock was originally confined to the D.C. Jail in connection with theft charges, but was extradited to Prince George's County Friday on a bench warrant, Smith said. Smith did not know the reason she was wanted in Prince George's.

Blalock was transferred to the Prince George's sheriff's department first, Smith said, and arrived at the Upper Marlboro facility around 6 p.m., the same time that those in the weekend work program were arriving.

"She apparently conned or convinced someone that she was a weekender," Smith said. So by 7:30 a.m. yesterday, Blalock was loaded into a truck with those in the weekend work program.

About an hour later, she told the truck driver that she needed to use the restroom, Smith said. He let her out at a business near the corner of Central Avenue and Brightseat Road in Landover, but she never reappeared.

Sixteen deputies were called in to search the county and the D.C. police were alerted as well, Smith said. Checking out tips and Blalock's known hangouts, D.C. police found her around 2 p.m. at 1252 Barnaby Ter. SE.

She remains in the D.C. Jail awaiting extradition back to the Prince George's County jail, this time was an additional charge of escaping, Smith said.

Blalock's escape was the third since the $43 million jail, called "escape-proof" by officials, was opened Feb. 28. An internal investigation was ordered after the May 26 breakout of John Raymond Reavis, 24, and Thomas Richard Emmett, 32, who climbed over two razor-wire fences during the night. Both were eventually captured.
